To (Ill whom it may concern Be it known that l. (funnies l1. NnnoMA, a citizen of the United States, residing in the city and county otSau Francisco and- State of California, have invented new and useful Improvements in Methods for Econo mixing Fuel and Preventing Carbon Deposits iu Explosive-l lugines, of which the following is a specification.

This invention relates to a method for economizing hydrocarbon fuel and preventing the. formation of carbon deposits-Within the cylinders and valves of internal combustion engines.

The object of this invention is to provide a method for i-nt'roducin free oxygen and steam into the inlet mani old of a gas engine for the purpose of causing the completethe vaporized hydrocarbon fuel in the engine and thereby-preventing the f rmation of'carbon deposits within the cvlinders and valves and at the same time increasing the power cfiiciency of the fuel. appear hereinafter. I

The invention primarily resides in subjecting H 0 (perox'id of hydrogen) to a sufiicient temperature to'liberate one of the oxygen atoms and convert the remaining H 0 into steam and introducingthe mixture of stea'mand oxygen into'thej. manifold of the engine. v

The invention will be more fully explained hv reference to the accompanying drawing, in which the figure is a side elevation of a gas engine showing the application of the invention.

Referring to the drawings, A indicates a standard type of internal combustion engine, provided with the usual form ofinlet manifold 2 and exhaust pipe Suitably supported above the engine in any convenientposition is a tank 4, provided with a filling opening which tank formsacontainer for I-I. ,O (peroxid of hydrogen).

(onnectin with the tank 4 and inlet manifold 52 1s a pair of pipes (land 7; the pipe 6 leading from a regulating valve 8. opening to the tank 4. to a steam generator 9 connecting the pipes 6 and 7. The valve 8, is provided with a sight feed attachment 10 so that the amount of H 0 fed to a steam generator 9 can be readily seen; a downcolnbustion of Further objects will Specification of EetteralPatent.

13 on its interior,

generating property or through pipe wardly opening, normally closed check-valve 11 being provided at the conjunction of the pipe 6 and casing o fthe sight feed 10. :This "valve 11 opens bysuction induced in the, manifold bv the engine pistons and automatically closes when the engine is not runnin to revent'exc'essoil-I 0 being delivere to t e steam generator- 9. A vent pipe 12 leads from the casing oftlie valve 8 and insures a constant uniform fiowof thell fl I through the valve 8 i the sight feed 10.

The steam generator 9 may be; of any su'it but preferably compr ses an able character inelosed casing havmg ,el trio heating coils to an electric generator- 1.4 oi any suitable yp v In operation, after the engine has been tarted, the vacuum ihduoedin the manifold the. reciprocation of the engine pistons will cause the check-valve 11 to 0 on and will draw a quantity of the H 0 elivered from the tank 4 through the valve Sinto the pipe 6 and throu h the steam genera tor 9.. The amount ofdl o passing through thevalve is regulated to such a quantity as occasion may require, the TLC) being fed usually in dro through the sig it feed attaoh'mentm. The 11 0 on being brought into direct contact with the hot 0011s of the heater 9 is immelllfilly converted into oxygen and steam, the oxygen being quickly liberated on the rise of temperature of the H 0 The mixture of oxygen and steam thus obtained is sucked 7 directly into the manifold 2 and will there mix with the vaporized hydroiarbon fuel therein and will then be drawn through the inlet valves into thc'engine cylinders where combustion takes place.

The admission of steam and free oxygen into the manifold produces a more perfect combustible mixture thanis ordinarily secured, and accumulations of carbon in the engine cylinders will be absolutely prevented by reason of the aflinity of carbon for free oxygen when heated to a high temperature. In actual ractice it hasbeen found that the steam a mitted to the engine cylinders has a tendency to absorb any soot wh ch .ppils'areyqonnected s, which are readily seen formed within the cylinders which would otherwise settle on the walls of the cylinders and the or carbon that may not be combusted by reason of insuflicient oxygen will be dischar (1 through the exhaust valves and exhaust pipe and,.therefore, any-bakin or formation of solid carbon deposits wil be entirely obviated.

Any quantity of the H 0 as maybe necessary to supply a'suflicient quantity of free oxygen to the vaporized hydrocarbon fuel to insure its complete combustion can be delivered to the heater 9 by adjusting the regulating valve '8.

in a series of recent tactical. tests it was found that where H 2 has been used in conjunction with hydrocarbon fuehes here- I inbefore described, the efficiency of the fuel was increased approximatelytwenty-five er cent, that is to say, greater speed with ess consumption of fuel was attainable where H 0 was employed than where only hydrocarbon fuel was used.

By the use of thisinvention the cost of -running the engine is reatly reduced on account of the saving 0' fuel; the value of' the quantity of fuel saved being much in excess of the cotbf-the quontitv of H O used. This, in conjunction with the prevention of carbon deposits in the engine cylin- I de rs tenders the invention ad vantngeous and important.

Having thus described my invention, what I claim and desire to secure by Letters Patent is- 1. The-method of increasing combustibility ofhydrocarbon fuels and preventing carbon deposits in explosive engines consisting in heating H O (peroxid of hydrogen) to liberate oxy 'en therefrom, converting the remaining H 6 into steam, and mixing the steam and oxygen with the vaporized hydro carbon fuel.

2. The method of increasing combustibil- 'iry of hydrocerbon fuels and preventin carbon deposits in explosive enginos'whic con- SiF-l'r in subjecting H O to heaVtoQliberate oxygen and then in converting the 'emain (ler' nto steam and introducing the'steam and oxygen mto the manifold of the engine. ln testimony whereof lhevehereunto set my hand in the presence of two subscribing witnesses.
